5' nois have invented certain new and useful Improvements in Fillers forEgg-Crates; and I do declare the following to be full, clear, and

' exact description of the invention, such as will enable others skilledin the art to which aplpertains make and use the same.

s invention relates to improvements in fillers for egg crates. Theobject of the invention is to ovide an egg crate filler, the parts ofwhic have roved locking devices by means of which they are-securely heldtogether against'casual. disengagement. With this'ohject in view, theinvention consists of certain novel features of construction,combination and arrangement of pal-tans be more fully described and pluticularly pointed out in the appended aims. Y

In the accompanying drawings, Figure 1' is a perspective view of onecorner of a filler constructed in accordance with the invention; Fig. 2is a side view of one of the outcross strips of the filler; Fig. 3 is asimilar view of one of the intermediate cross strips which run in onedirection; and Fig. 4

is a similar view of one of the intermediate cross strips which run inthe opposite'direc- 125% at right-angles to ,the strips shown in 1 3 nthe embhdiment of the invention-I vide a series of stripsll formed ofpasteboard orlsimilar material,- aiadada ted to form two sides of theegg cells.

ends to form the outer walls of the corner egglcells of the filler..

ach of the stri s1 are provided at suitable intervals wit vertical rowsof triangular perforations 4, which extend upwardlyfrom the lower ed esof the stri s to a point slightly abovert e centers of t e r Theperforations 4 are arranged in the strips so that one of theright-angular walls, 5, thereof will be in line with each 55 other,while the other right-angular walls, 6,

.ton

, to be enga right-anglesintheopposite direction. Above the row ofperforations 4, the strips 1 are cut to form a'zig zag series-of lockingtongues 7. The zig-zag out which forms the tongue 7 is continuous fromthe upper perforation 4 to the upper edge of the strip.

The stri s 2 run at 1'1 ht an les to the strips 1 an are also provi edwit a series of vertically disposed triangularly shapedperforations 8,said rows being spaced apart at suitable intervals.'- The perforations Bin the strips 2 extend downwardly from the upper ed e of the strips andhave their vertical wa s 9 arranged in alinement, while the horizon'talwalls 10 of each alternate perforation projects in op osite directionsat right-angles Below the row of. erforations 8 is formed a zig-z-ag outw h extends continuously from the lower perforation 8 to the lower ed eof the strip and forms .a series of angular T' e arrangement of theperforations 8 and the locking tongues 12 in the strip 2 is ex actlyopposite to the arrangement of the per? forations 4 and locking tongue 7of the strip 1, so that when said stri s are brought to gether to formthe cells 0 the filler, the cut portions of said strips are slippedtogether or into engagement, after which the looking tongues in the uper portion of the strip 1 will engage with the per portion of the strips2, and in like manner the. locking tongues in the lower portion ofthestri-p 2 will spring into engagement with the erforations 4 in thelower a of the strip 1, thus providing for a 10 ed engagement betweenthe. opositel' disposed y shaped locking seplaration of said strips.

of each alternate perforation projects at perforations in the up- Irtion he outer opposite ends of the strips 1 and 2 are provide withdovetail-shaped. lockin heads or pro'ections 13, which are adapte edwith lockin slots, 14, formed in outer er strips 15, w 'ch are arran edaround the outersides or edges of the ler and form the outer wall of theouter row of e g cells. The locking heads 13 on the ends 0% the strips 1and 2 are notched inwardly to form looking recesses, 16, while the slots14 in the outer strips 15 are cut attheir o 0- site ends to formangularly shaped mg tongues, 17, which are adapted to engage thetail-shaped slots 14 in the opposite ends of the other two outer strips15 at each corner of the'filler, the tongues 17 of said outer slotsbeing engaged with the notches 19 in the head, 18, thereby securelylocking the ends of the outer strips 15, together and forming the outerWalls of the corner egg cells.

The ends of each of the strips 1 and 2 roject above and below the heads13 to orm,

protecting lugs 20, saidlugs being adapted to project over the upper andlower edges of the outer strips 15, sa1 strips being cut inwardly oneach side of the point which is engaged by the lugs 20, as shown at 21,said material between the cuts 21 being adapted to be bent outwardly atright-angles to the strip to permit the engagement of the lugs 20 withthe latter. The lugs 20 together with the outwardly bent out portions ofthe strips 15 form protecting lugs for the locking heads 13 and preventsaid heads from coming into engagement with the inner sides of the cratewhen the fillers are placed therein.

Having thus described my invention, I claimz 1. In an egg crate filler,a series of intermediate cell strips arranged at right-angles to eachother to form egg cells, said strips having vertical rows of lockingapertures arranged at intervals, a series of locking tongues arranged inline with each of said rows of apertures, said tongues being formed byzig-zag cuts extending from the inner end of each row of lockinapertures to the opposite edge of the strip, 0 king heads formed on theends of said intermediate cell strips,'outer cell strips arranged aroundthe edges of the filler, said strips having formed therein looking slitsto receive the heads'on the ends of the intermediate strips, and meansonsaid outer cell strips to protect the locking heads on saidintermediate strips, substantially as described.

2. In an egg crate filler, a series of intermediate cell strips arrangedat right-angles to said intermediate strips,

formed on the opposite ends of two of said each other to form e g cells,said strips having vertical rows 0 locking apertures arof each row oflocking apertures to the opposite .ed e of the strip, locking headsformed on sai intermediate cell strips, said heads having lockingnotches formed therein, outer cell strips arranged around the edges ofthe filler, said strips having a series of vertically disposed slotsformed therein to receive the heads on the intermediate cell strips,locking tongues formed at the ends of said slots to engage the-notchesin the locking heads of outer cell strips to engage the outer end slotsof the other two outer stri s, thereby forming the corner cells of theer, and means on said outer cell strips to protect the locking heads onsaid intermediate cell strips, substantially as described. I

3'. In an egg crate filler, a series of. intermediate cell stripsarranged at right-angles to each other to form intermediate egsaidstrips having vertical rows of ockingv apertures arranged atintervals, a series of locking tongues arranged in line with each ofsaid rows of apertures, said tongues being formed by zig-zag cutsextending from the 8 inner ends of each row of apertures to the oppositeedge of the strip, locking heads formed on the ends of said intermediatecell strips,

protecting lugs formed on the ends of said strip above and below saidlocking heads, 0

outer cell strips arran ed around the edges of the filler, said stripsaving formed therein locking slits to receive the heads on the ends ofthe intermediate strips, and laterally projecting pieces formed on saidouter strips and held in position by said lugs to protect the lockingheads on said intermediate strips, substantially as described.

In testimony whereof I have hereunto set,
